Just for my own education, how is the geometry different on say a Global west setup from a setup with the stock type upper arm dropped 1.75" and a ball joint wedge?
Where are the massive performance gains coming from? The coil over itself?
The actual optimum number for the drop is closer to 1.5"...... the extra 1/4" that the
wedge kit suggests is too far.
The spring is actually a softer item for most applications. (540#)
The geometry of the GW arm is different. At the end is the obvious difference,
the angle of the ball joint is addressed. Much less noticeable, the GW arm is shorter
than the factory arm. It isn't much, but a small difference in this area yields a major
difference in camber curve.
No matter what you do with a stock length arm, you can't address the fact that the
length is wrong. Consequently, all you can do is put in a high rate spring, slowing the
oncoming positive camber gain. You can't generate a negative camber gain. You
will not maintain tire contact patch and your cornering WILL suffer.
There also is the difference of the bushings vs. steel on steel of the factory setup.
You eliminate squeaking and free up the suspension at the same time.
A 289HP car with the GW setup will walk away from a 65/66 Shelby on a road course
if they both have the same tires/wheels. It's not even a close contest.
